Chronic oxygen deficiency is defined as a prolonged lack of oxygen to the body as that occurs in living in high altitudes or by having severe chronic lung disease. Chronic oxygen deficiency have the following effects : There is decreased mental efficiency due the prolonged deficiency of oxygen Sleepiness, headache, lassitude and fatigubility are also common Euphoria is also […]
There are 4 types of Hypoxia . The 4 types of Hypoxia are as follows: 1. Anoxic hypoxia or Diffusion hypoxia Anoxic hypoxia also called as diffusion hypoxia is essentially due to the deficiency of oxygen being absorbed by the lungs. This is either due to a decrease in the inspired concentration of oxygen in the air
Following are the Hypoxia signs Psychological Hypoxia signs – Higher centers are first impaired in hypoxia due to deficiency of oxygen to the brain tissue. Psychomotor and emotional judgement is poor in the absence of oxygen. The mechanisms mediating cerebral vasodilation during hypoxia are not fully understood but may include neurogenic effects initiated by peripheral and neuraxial chemoreceptors,
The preparation of carbon dioxide gas is needed before it is actually stored in cylinders. The preparation of carbon dioxide gas is done though following steps : 1. From fermentation in the brewing of beer 2. By-product of manufacture of hydrogen in petroleum refining 3. Combustion of other fuels 4. By heating magnesium and calcium
Nitrogen is present in the atmosphere and it constitutes 78.08% of total air. Moreover, the use of nitrogen is growing very rapidly these days. Use of nitrogen in medicine is helpful as it can be used as diluent of oxygen in order to avoid oxygen toxicity. It is stored in either compressed air or in
There are numerous uses of carbon dioxide in modern anesthesia. It is used : • To increase depth of anesthesia with volatile anesthetic agents by stimulating respiration.- • To increase cerebral blood flow during carotid artery surgery. • To produce hyperventilation during blind nasal intubation. • To stimulate the respiration after artificial hyperventilation. • It
In the atmosphere it is present in the concentration of 0.003%. It is stored as high pressure gas in the cylinders. There are several effects of helium Inhalation . The medical diagnostic utility is secondary to its low density, insolubility and thermal conductivity. • Molecular weight is 4. • Specific gravity is 176. • It
Nitric oxide Inhalation may cause selective reversible dose-dependent pulmonary vasodilatation. It improves ventilation and perfusion of lungs, so beneficial in adult respiratory distress syndrome. It helps to reduce pulmonary vascular resistance in patients with primary pulmonary hypertension. It was known to be atmospheric pollutant produced by internal combustion of engines. It possesses various biological functions—there
Common health effects of carbon dioxide include : • There is fall in peripheral vascular resistance but there is increase in mean arterial pressure. There is increase in blood flow towards skin and so more chances of oozing. • Directly it reduces contractile force of heart but indirectly increases cardiac output. It increases the sympathetic
Carbon dioxide was discovered by Von Helmont and was isolated by Joseph Black in 1757. Physical properties of carbon dioxide were shown by Yandell Henderson in 1925 and J S Haldane in 1926. It was frequently used to stimulate respiration and there was provision for carbon dioxide cylinders on old Boyle’s machines. The physical properties of
